Abstract
Description
本願は、2013年2月28日に出願された特願2013-39617号に基づき優先権を主張し、その内容をここに援用する。
この種の用途で交流発電用の回転電機を用いる場合には、回転電機を円滑に駆動させるために、ロータ上の永久磁石の移動位置に応じてステータ側のU相,V相,W相の各磁極のコイルに適正なタイミングで通電を行う必要がある。このため、この種の用途で用いられる回転電機においては、ロータの回転位置を検出するための位置検出センサが設けられている(例えば、特許文献1参照。)。
また、この特許文献1に記載の回転電機の場合、有底円筒状のロータが、そのロータの開口側がクランクケース側を向くようにしてクランク軸の端部に取り付けられており、ステータとそのステータに付設されるホールICユニットとはクランクケースの壁部の外側面に取り付けられている。ステータやロータは、クランクケースの壁部に取り付けられるエンジンカバーによってこれらの外側を覆われている。
(1)本発明の一態様に係るエンジンユニットのセンサ設置構造は、クランク軸を収容するクランク室と前記クランク軸の端部が突出する開口とを有するクランクケースと;前記開口から突出した前記クランク軸の前記端部に取り付けられる有底円筒状のロータと前記ロータに近接する非回転部に取り付けられるステータとを有する回転電機と;前記ロータの回転位置を検出する位置検出センサと;前記クランクケースの前記開口のある壁部に取り付けられて前記クランク軸の前記端部と前記回転電機の外側を覆うエンジンカバーと;前記位置検出センサが、前記ロータに設けられた永久磁石と;前記ロータ上の前記永久磁石の回転位置に応じた磁束の変化を検出するホールICユニットと;を備え、前記クランクケースの前記開口に、前記クランク室と前記エンジンカバーの内側空間とを隔成する隔壁が設けられ、前記ロータは、前記クランク軸の前記端部に、底壁が前記クランクケース側に位置されるように取り付けられ、前記回転電機の前記ステータと前記位置検出センサの前記ホールICユニットとが前記エンジンカバーに取り付けられ、前記ロータと前記隔壁の間に、前記ロータの前記底壁と前記隔壁の間の空間に冷却風を誘導するための強制冷却用の導風部材が設けられている。
これにより、クランク室とエンジンカバーの内側空間の間が隔壁によって仕切られ、クランクケース内を流動する高温の潤滑オイルがエンジンカバー内に流入するのを規制される。また、ステータとホールICユニットは、外気に晒されて冷却され易いエンジンカバーに取り付けられていることから、温度上昇を抑制できる。また、ロータの底壁と隔壁の間の空間部には、導風部材によって強制冷却風が導入され、エンジンカバーの内側に臨む隔壁の周辺部が強制冷却風によって冷却される。この結果、クランクケース側の熱がホールICユニット側に伝達されにくくなる。
これにより、回転羽根と整流羽根との協働により、隔壁の前面側において、冷却風を効率良く流動させることが可能になる。
これにより、車両の走行時には、走行風が導風ダクトを通してエンジンカバー内のクランク軸に対向する方向に導入され、その走行風の一部が、ロータの底壁の貫通孔を通して隔壁方向に直接流入し、残余の走行風が、ロータの底壁で向きを変えてホールICユニットの周域方向に流れる。貫通孔から隔壁方向に流入した走行風は、隔壁を冷却した後に、排出口からエンジンカバーの外部に排出される。また、ホールICユニットの周域に流れ込んだ走行風は、ホールICユニットを冷却した後に、ロータの周壁の外側に回り込んで排出口からエンジンカバーの外部に排出される。
これにより、ロータ側の永久磁石がU相,V相,W相の各磁極の近傍を通過するタイミングがホールICユニットのホールIC素子を通して検出されることになる。
これにより、ピックアップセンサの検出信号を基にしてエンジンの点火タイミングが検出されるようになるとともに、ピックアップセンサの検出信号と各ホールIC素子の検出信号とを組み合わせることによって、クランク軸の回転角度も検出可能となる。
これにより、クランクケース側からエンジンカバー側に伝達されようとする熱を隔壁が遮断するようになる。また、隔壁には導風部を形成し易くなる。
(車両構成)
図1は、エンジンユニット2を搭載した自動二輪車1の側面を示す図である。
自動二輪車1は、エンジンユニット2が車体前後方向の中央に搭載され、エンジンユニット2の後部上方に乗員が着座するシート3が設けられ、シート3の下方に燃料タンク4が設けられている。
前輪Wfは、フロントフォーク5に回転可能に支持され、フロントフォーク5の上部に操舵ハンドル6が設けられている。後輪Wrは、スイングアーム7を介して車体フレームに揺動可能に支持されている。
図2は、図1のA-A断面に対応するエンジンユニット2の断面図である。
エンジンユニット2は、内燃機関であるレシプロ式のエンジン10と、多段式の変速機11が一体ブロックとして構成され、エンジン10と変速機11が遠心クラッチ8とミッションクラッチ12を介して動力伝達可能とされている。
図2に示すように、燃焼室19内に臨むようにシリンダヘッド20には点火装置21が設置される。シリンダヘッド20の端部には動弁装置22が設けられる。動弁装置22は、クランク軸16と連動して図示しない吸排気バルブを開閉駆動する。クランク軸16上のコンロッド15との連結部(クランクピン)の軸方向両側にはクランクウェブ23が設けられる。クランクケース17内のクランク室17aは、クランク軸16の実質的に全域を収容する。
また、クラッチアウタ25には、ミッションクラッチ12の入力ギヤ27と噛合する出力ギヤ28が一体回転可能に結合されている。
変速機11では、クランクケース17内に設けられた図示しないシフトドラムの回動操作によってメイン変速ギヤ群M1とカウンタギヤ群M2の駆動伝達ギヤが選択され、それによってニュートラルを含む任意の変速ギヤ段(ギヤポジション)が設定される。
ACGスタータ50は、クランク軸16の端部に取り付けられる有底円筒状のロータ52と、ロータ52の内周側に配置されるステータ53と、を備えている。ロータ52は、底壁52aがクランクケース17の側壁側に位置されるようにクランク軸16に固定される。ステータ53は、エンジンカバー51の底壁51aの内側面にボルト締結等によって固定されている。
これらの図に示すように、ステータ53は、放射方向に突出する複数のティース55を有し、その各ティース55にU相,V相,W相のいずれかのコイル56が巻回されている。各ティース55の先端面は、ロータ52の内周の永久磁石54の磁極面に微小隙間をもって対峙するようになっている。
なお、本実施形態においては、各ホールICユニット57の一パッケージの樹脂57bに対応するホールIC素子57aが一つずつ埋設されているが、U相用,V相用,W相用の3つのホールIC素子57aを一パッケージとして樹脂57b内に埋設するようにしても良い。
ピックアップセンサ62で検出される検出信号は、前述の3つのホールICユニット57で検出される各信号と併せてクランク軸16の回転角を検出するのにも用いられる。すなわち、ピックアップセンサ62では、エンジンカバー51に対するクランク軸16の特定角度を検出することができるため、ピックアップセンサ62から検出信号が出力されてからの各ホールICユニット57の検出信号のパルスをカウントすることにより、クランク軸16の特定角度を起点とした複数ヶ所の角度を検出することができる。
エンジンカバー51の底壁51aの実質的中央部には、図3に示すように、クランク軸16の軸方向の端部と対向するように外気導入孔69が形成される。底壁51aの車外側には、車両走行時に走行風を外気導入孔69を通してエンジンカバー51内に取り入れるための導風ダクト59が取り付けられている。導風ダクト59は、外気を取り入れる先端部側が車体前方側に指向している。また、エンジンカバー51のクランク軸16よりも後方側の壁には、エンジンカバー51内に導入された走行風を外部に排出するための排出口60が設けられている。
図3,図6に示すように、隔壁63のロータ52の底壁52aと対向する側の面には、ロータ52側のフィン67から送られた冷却風の流れを整流する円弧状の整流羽根68が突設されている。本実施形態の整流羽根68は、ロータ52側のフィン67の形成位置よりも径方向外側に配置されるとともに、ロータ52側のフィン67と軸方向で相互にオーバーラップする。このため、フィン67から隔壁63の前面に冷却風が吹き付けられると、冷却風は、整流羽根68による案内機能により、隔壁63の前面に沿って車体後方領域に誘導される。このように隔壁63の前面に沿って流れる冷却風は、隔壁63とその周域部を冷却した後に排出口60を通してエンジンカバー51の外部に排出される。
なお、導風ダクト59からエンジンカバー51内に取り入れられた走行風は、エンジンカバー51の周壁の内面に取り付けられたピックアップセンサ62も冷却する。
なお、ピックアップセンサ62と各ホールICユニット57の各検出信号を基にして検出されるクランク軸16の回転角度は、例えば、アイドルストップ時に、クランク軸16の停止位置(角度)が次のエンジン10の再始動に適した位置になるように、ACGスタータ50を回転制御する場合に用いられる。
本実施形態のエンジンユニットは、基本的な構成は第1の実施形態と実質的に同様であるが、第1の実施形態では、回転羽根として機能するフィン67がロータ52の底壁52aに一体に設けられているのに対し、ロータ52と別体の回転羽根77がクランク軸16に一体に取り付けられている点が異なっている。
回転羽根77は、クランク軸16に固定される円板状の支持板75に複数のフィン67が突設されたものであり、ロータ52の底壁52aと隔壁63の間の空間部に位置されるように、クランク軸16上に取り付けられている。
本実施形態の場合、回転羽根77がロータ52の底壁52aと隔壁63の間の空間部に冷却風を誘導する導風部材を構成している。
また、隔壁63の前面側には、第1の実施形態と同様に整流羽根68が突設されている。整流羽根68は、回転羽根77よりも径方向外側に配置されるとともに、回転羽根77に対して軸方向でオーバーラップするようになっている。
なお、隔壁63には、第1の実施形態と同様に、回転羽根77から送られた冷却風の流れを整流する整流羽根68を設けるようにしても良い。
第4の実施形態のエンジンユニットは、エンジンの点火タイミングを検出するために、図3,図8に示すピックアップセンサ62を採用せずに、ACGスタータ50の永久磁石54の一部に検出ターゲット用の指標磁石91(永久磁石)を付設し、その指標磁石91を含む磁石列の磁束変化をホールICユニット57Aによって検出するようにしている。本実施形態では、指標磁石91を含む永久磁石54の磁石列とホールICユニット57Aが、ロータ52の回転位置を検出する位置検出センサ58Aを構成している。なお、本実施形態の場合、永久磁石54とU相用,V相用,W相用の各ホールICユニット57(以下、「通電制御用のホールICユニット57」と呼ぶ。)は上記の他の実施形態と同様に位置検出センサ58を構成している。
また、本実施形態の場合、ロータ52の外周壁に、エンジンの点火タイミングを検出するためのターゲット用の凸部を加工する必要がないため、製造コストの削減が可能になるという利点もある。
